The world-renowned sports brand was founded in 1911 by the FILA brothers in BIELLA, Italy, and has a history of more than 100 years. FILA is mainly engaged in the development of sports-related products such as tennis, skiing, golf, yoga, and fitness. The FILA HIIT trainer is designed with lightweight wrapping and dynamic support as its core selling points, and the upper has a simple design style, and the lightweight and seamless film makes the whole shoe light and breathable. The double-layer structure on both sides and the inner shoe design provide sufficient support and protection to improve the wrapping and stability of the upper. The design of the midsole is inspired by the elastic principle of a fitness ball, combined with high-elastic PU material, which is soft and lightweight, and has good rotation and bending performance. The men's diamond pattern and the women's lizard paw pattern are non-slip and grip to meet the needs of anti-rollover and wear-resistant during sports. At the same time, taking into account the characteristics of female consumers' feet, the women's version of the last is more slender and delicate than the men's version.
